This package provides an ActionCable context provider and consumer to allow you to subscribe to ActionCable channels in your React components.
As this package uses React's new Context API, React 16.3+ is required.
npm install --save react-actioncable-provider
# OR
yarn add react-actioncable-providerThe public API exports two components that you'll use: <ActionCableProvider /> and <ActionCableConsumer />.
The provider is used in an outer container and wraps all of the components that may or may not consume the context. It accepts one of two props: url and cable. Passing url will result in the provider instantiating its own ActionCable.Consumer with that URL. Passing cable allows you to manually instantiate an ActionCable.Consumer on your own and pass it to the provider to be used by all descendent consumers.
<ActionCableProvider url="ws://test.example.com/cable">...</ActionCableProvider>import ActionCable from 'actioncable';
const cable = ActionCable.createConsumer('ws://test.example.com/cable');
<ActionCableProvider cable={cable}>...</ActionCableProvider>;The consumer will wrap an individual component. It accepts several props:
channel[String] Name of the channel to which you want to subscribe.channel[Object] An object with achannelkey which denotes the channel to which you want to subscribe. All other keys are passed to the channel as params.onConnected[Function] A handler function that is called when the channel connects.onDisconnected[Function] A handler function that is called when the channel disconnects.onInitialized[Function] A handler function that is called when theActionCable.Consumeris initialized.onRejected[Function] A handler function that is called when the requested subscription is rejected.onReceived[Function] A handler function that is called when the channel transmits a message to the client.
